🔧 Dependencies and Installation

1. Clone repo

   git clone https://github.com/Fanghua-Yu/SUPIR.git
   cd SUPIR
   

2. Install dependent packages

   conda create -n SUPIR python=3.8 -y
   conda activate SUPIR
   pip install --upgrade pip
   pip install -r requirements.txt
   

3. Download Checkpoints

For users who can connect to huggingface, please setting LLAVA_CLIP_PATH, SDXL_CLIP1_PATH, SDXL_CLIP2_CKPT_PTH in CKPT_PTH.py as None. These CLIPs will be downloaded automatically.

Dependent Models

• SDXL CLIP Encoder-1
• SDXL CLIP Encoder-2
• SDXL base 1.0_0.9vae
• LLaVA CLIP
• LLaVA v1.5 13B
• (optional) Juggernaut-XL_v9_RunDiffusionPhoto_v2
  • Replacement of SDXL base 1.0_0.9vae for Photo Realistic
• (optional) Juggernaut_RunDiffusionPhoto2_Lightning_4Steps
  • Distilling model used in SUPIR_v0_Juggernautv9_lightning.yaml

Models we provided:

• SUPIR-v0Q: Baidu Netdisk, Google Drive

  Default training settings with paper. High generalization and high image quality in most cases.

• SUPIR-v0F: Baidu Netdisk, Google Drive

  Training with light degradation settings. Stage1 encoder of SUPIR-v0F remains more details when facing light degradations.

1. Edit Custom Path for Checkpoints

   * [CKPT_PTH.py] --> LLAVA_CLIP_PATH, LLAVA_MODEL_PATH, SDXL_CLIP1_PATH, SDXL_CLIP2_CACHE_DIR 
   * [options/SUPIR_v0.yaml] --> SDXL_CKPT, SUPIR_CKPT_Q, SUPIR_CKPT_F

Empirical Hyperparameters Settings

• The parameters listed generally have significant impact on the final image quality and appearance.

1. s_stage2 adjustment:

   Option 0: s_stage2 = 1.0 (higher fidelity, potentially lower visual quality)

   Option 1: s_stage2 = 0.93 (higher visual quality, potentially lower fidelity)

2. Quality-oriented settings (higher visual quality, potentially lower fidelity):

   s_cfg = 6.0, spt_linear_CFG = 3.0, s_noise = 1.02

3. Fidelity-oriented settings (closer to original input fidelity, may sacrifice some visual appeal):

   s_cfg = 4.0, spt_linear_CFG = 1.0, s_noise = 1.01

Python Script

# Seek for best quality for most cases
CUDA_VISIBLE_DEVICES=0,1 python test.py --img_dir '/opt/data/private/LV_Dataset/DiffGLV-Test-All/RealPhoto60/LQ' --save_dir ./results-Q --SUPIR_sign Q --upscale 2
# for light degradation and high fidelity
